Canadian singer Justin Bieber performs in a concert at the Manchester Arena in Manchester, northern England, February 21, 2013.

Justin Bieber has a new X tattoo to join his previous inkings. The 18 year old singer was spotted with the new tattoo as he was leaving a Cirque du Soleil show in London Monday night. A photo of his new tattoo has now gone viral as his legions of fans look to see the star's latest ink.

The new tattoo follows the three new tattoos he had done in just January, which included the Roman numerals of his mom's birth year on his collarbone, a Native American wearing a head dress on his upper left shoulder, and a rose on his leg.

The new "X" tattoo has been put below a larger tattoo of an owl on his left forearm.

The news of the new tattoo comes after Patrick Carney enraged many Justin Bieber fans after he changed his Twitter profile to mock them.

The Black Keys drummer changed his Twitter profile to Justin Bieber's name and posted a picture of the Canadian crooner as his profile photo. He also added "official twitter for the actual verified Justin Bieber DOS virtual buddy" to the profile.

There has been ample social media tension between Bieber fans and Carney, especially after Carney suggested that Bieber did not deserve any Grammy Award nominations for his work.

That obviously did not go down well with Bieber fans who jumped to his defense and mocked Carney on numerous blogs and social media posts.

Soon after, Carney also did the trick of changing his Twitter profile to Bieber, and that led to even more backlash against the Black Keys drummer.

As for Bieber, he seems to be ignoring the entire thing and has not reacted to Carney's attempts to instigate some controversy between the two.
